Description
Die Erfindung geht aus von einem Verfahren und Vorrichtung zur Fahrerunterstützung vor und/oder bei Durchfahren einer Engstelle.The invention is based on a method and device for driver support before and / or when driving through a bottleneck.
Es ist bereits bekannt, in Kraftfahrzeugen eine Vielzahl von Sensoren zur Umgebungswarnung einzubringen. Für die Messung der Entfernung zwischen einem Fahrzeug und Hindernissen bei einem Einparkvorgang sind Ultraschallsensoren bekannt. Für ein abstandsgeregeltes Folgefahren werden Radarsensoren oder Lasersensoren eingesetzt, in Abhängigkeit von deren Messdaten die Fahrzeuggeschwindigkeit an die Geschwindigkeit eines vorausfahrenden Fahrzeugs angepasst wird. Ferner sind Kamerasysteme bekannt, die Objekte in der Fahrzeugumgebung detektieren und auswerten. Diese Sensoren zur Umfeldüberwachung dienen im Allgemeinen dazu, Hindernisse zu detektieren und dem Fahrer den Abstand zwischen seinem Fahrzeug und den Hindernissen bzw. die Geschwindigkeit gegenüber den Hindernissen anzuzeigen.It is already known to introduce a large number of sensors for environmental warnings in motor vehicles. Ultrasonic sensors are known for measuring the distance between a vehicle and obstacles when parking. For distance-controlled following driving, radar sensors or laser sensors are used, depending on their measurement data, the vehicle speed is adapted to the speed of a vehicle ahead. Furthermore, camera systems are known that detect and evaluate objects in the vehicle environment. These sensors for monitoring the surroundings are generally used to detect obstacles and to indicate to the driver the distance between his vehicle and the obstacles or the speed in relation to the obstacles.

Offenbarung der ErfindungDisclosure of the invention
Die Fahrerunterstützung ist individualisierbar ausgestaltet und wird an den Fahrer bzw. dessen Fähigkeiten angepasst. Dies hat den Vorteil zu verhindern, dass ein geübter Fahrer durch Eingriffe oder Hinweise gestört wird, während ein ungeübter Fahrer dennoch eine wirksame Unterstützung erhält.The driver support can be customized and is adapted to the driver or his skills. This has the advantage of preventing an experienced driver from being disturbed by interventions or instructions, while an inexperienced driver still receives effective support.
Besonders vorteilhaft ist, dass der Fahrer während der Durchfahrt bei längeren Engstellen, insbesondere bei sich bewegenden und sich ändernden Engstellen, wie z.B. beim Überholen eines Lkw in einer Autobahnstelle mit verminderter Spurbreite, je nach seinen Fähigkeiten wirksam unterstützt wird. Dabei erfolgt ein fortgesetztes Messen des oder der Abstände und daraus abgeleitet eine individualisierte Fahrerinformation und/oder ein individualisierter Fahrzeugeingriff.It is particularly advantageous that the driver is effectively supported depending on his or her abilities while driving through long bottlenecks, especially in moving and changing bottlenecks, such as when overtaking a truck in a motorway junction with a reduced lane width. In this case, the distance or distances are continuously measured and, derived therefrom, individualized driver information and / or an individualized vehicle intervention.
Die Individualisierung wird in einer bevorzugten Ausführung dadurch erreicht, dass das Ausmaß der Unterstützung des Fahrers beim Durchfahren einer Engstelle abhängig ist von dem Fahrerverhalten in einer oder mehreren ähnlichen Situationen in der Vergangenheit.The individualization is achieved in a preferred embodiment in that the extent to which the driver is supported when driving through a bottleneck depends on the driver's behavior in one or more similar situations in the past.
Weitere Vorteile ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen bzw. aus den abhängigen Ansprüchen.Further advantages emerge from the following description of exemplary embodiments or from the dependent claims.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigt
In der
In einer vorteilhaften Ausführungsform wird durch die Vorrichtung vor und/oder während der Durchfahrt einer Engstelle automatisch aktiv in die Längs- und/oder Quersteuerung des Fahrzeugs eingegriffen, z.B. durch aktive Steuereingriffe in den Motor und/oder die Bremsen zur Beschleunigung und/oder Verzögerung und/oder in die Lenkung zur automatischen Querführung.In an advantageous embodiment, the device automatically actively intervenes in the longitudinal and / or transverse control of the vehicle before and / or during the passage through a bottleneck, for example through active control interventions in the engine and / or the brakes for acceleration and / or deceleration and / or in the steering for automatic lateral guidance.

Stellt die Recheneinheit
Während der Durchfahrt der Engstelle ermittelt die Recheneinheit
Die Informationen an den Fahrer und/oder die Eingriffe sind wie unten dargestellt an das Fahrerverhalten bzw. die Fahrerfähigkeiten individuell angepasst.The information to the driver and / or the interventions are individually adapted to the driver's behavior or the driver's skills, as shown below.
In einer bevorzugten Ausführungsform werden die tatsächlich ermittelte Durchfahrtsbreite in der Anzeigeeinheit
Die Unterstützung des Fahrers in seiner Quer- und/oder Längsführung erfolgt je nach Ausführung durch Aufbringen eines in der geeignete Richtung weisenden Lenkmoments auf das Lenkrad, durch visuelle Lenkanweisungen z.B. in Form von Pfeilen, Einblenden einer idealen Fahrspur durch die Engstelle, akustische Anweisungen (z.B. Sprachanweisungen oder geeignete Töne). Eine Unterstützung in der Längsführung kann durch Beschleunigungs- oder Bremshinweise erfolgen, sofern sich der Abstand zu dem Hindernis in der Engstelle drastisch reduziert, so dass eine unveränderte Weiterfahrt nicht möglich ist. Letzteres wird je nach Verkehrssituation entscheiden, so dass z.B. bei Verkehr vor dem Fahrzeug bei enger werdender Engstelle ein Bremshinweis gegeben wird, bei freier Fahrt und nahem Ende der Engstelle ein Beschleunigungshinweis.The driver is supported in his lateral and / or longitudinal guidance, depending on the design, by applying a steering torque to the steering wheel pointing in the appropriate direction, through visual steering instructions e.g. in the form of arrows, fading in an ideal lane through the narrow point, acoustic instructions (e.g. Voice instructions or suitable tones). A support in the longitudinal guidance can be provided by acceleration or braking instructions, provided that the distance to the obstacle in the narrow point is drastically reduced, so that an unchanged Further travel is not possible. The latter will be decided depending on the traffic situation, so that, for example, when there is traffic in front of the vehicle, a braking warning is given when the bottleneck becomes narrower, and an acceleration warning is given when the vehicle is moving freely and the bottleneck is near.
In der
In einer besonderen Ausführung wird die Ausprägung der Fahrerunterstützung vor und/oder während der Durchfahrt der Engstelle
Ferner werden die Anweisungen bei der Durchfahrt häufiger ausgegeben (in geringerem Zeitabstand) und/oder gleichzeitig oder kurz hintereinander mehrere verschiedene Anweisungen gegeben, z.B. gleichzeitig ein Lenkmoment aufgeprägt und eine akustische Warnung ausgegeben. Im Sinne einer adaptiven Warnstrategie könnten einem unsicheren Fahrer auch während der Durchfahrt die Abstände mittels eines Balkendiagramms in einer Ampelkonstellation dargeboten werden. Gelb und rot würde dann schneller und häufiger erscheinen und grün dagegen seltener, damit dem Fahrer der Regulierungsbedarf kontinuierlich aufgezeigt wird. Das System könnte dem Fahrer auch anbieten Teile der Aufgaben (Bremskraftverstärkung) oder ganze Aufgaben (z. B. Lenken) zu übernehmen. Dies würde es dann gelten im Einzelfall zwischen System und Fahrer auszuhandeln. Ferner könnten die Informationen aus dem Fahrzeug
Furthermore, the instructions are issued more frequently when driving through (at a shorter time interval) and / or several different instructions are issued simultaneously or in quick succession, for example a steering torque is applied at the same time and an acoustic warning is issued. In terms of an adaptive warning strategy, an unsafe driver could also be shown the distances by means of a bar chart in a traffic light constellation while driving through. Yellow and red would then appear faster and more frequently and green, on the other hand, less often, so that the need for regulation is continuously shown to the driver. The system could also offer the driver parts of the tasks (brake force boosting) or entire tasks (e.g. steering) to take over. This would then apply to negotiate between the system and the driver on a case-by-case basis. It could also use the information from the

Das skizzierte Programmmodul wird eingeleitet, wenn anhand der Durchfahrtsbreite zwischen zwei Begrenzungen und/oder Hindernissen eine Engstelle erkannt wird. Dies erfolgt durch Vergleich mit einem Grenzwert, der vorgegeben ist. Das Programmmodul wird verlassen, wenn die Engstelle passiert ist, d.h. die Durchfahrtsbreite einen Grenzwert überschritten hat. Auch dieser Grenzwert ist vorgegeben und vorzugsweise größer als der erste Grenzwert. Im Schritt
Neben oder anstelle der oben dargestellten Auswertung eines Lenkwinkelsignal können andere Auswertungen, z.B. auf der Basis der Amplitude des Signals und Vergleich mit Grenzwerten eingesetzt werden.In addition to or instead of the evaluation of a steering angle signal shown above, other evaluations, e.g. based on the amplitude of the signal and comparison with limit values, can be used.
Neben oder anstelle von Lenkwinkelsignalen werden in anderen Ausführungen andere Signale ausgewertet, die auf eine unsichere Fahrweise schließen lassen, z.B. ein Geschwindigkeitssignal, ein Gaspedalstellungssignal, etc.. Dabei wird eine unsichere Fahrweise erkannt, wenn häufige Schwankungen des Signals ermittelt werden.In addition to or instead of steering angle signals, other signals are evaluated in other versions that indicate an unsafe driving style, e.g. a speed signal, an accelerator pedal position signal, etc. An unsafe driving style is recognized if frequent fluctuations in the signal are detected.
In der obigen Ausführung werden nur zwei Kategorien dargestellt (Marke gesetzt = unsicher, Marke ungesetzt = sicher). In anderen Ausführungen sind mehr Kategorien vorgesehen, so dass Zwischenzustände ermittelt werden können, wie z.B. „etwas unsicher“, „stark unsicher“, etc..In the above description only two categories are shown (mark set = unsafe, mark unset = safe). In other versions, more categories are provided so that intermediate states can be determined, such as "somewhat unsafe", "very unsafe", etc.
Nach Start des Moduls wird im ersten Schritt
In einer anderen Ausführung wird bei unsicherer Fahrweise Eingriffe in Quer- und/oder Längssteuerung des Fahrzeugs vorgenommen, bei als sicher bewerteten Fahrweise nur Hinweise dem Fahrer gegeben, auf automatische Eingriffe verzichtet oder deren Ausmaß (z.B. maximaler Korrekturwert des Lenkwinkels) eingeschränkt.In another embodiment, if the driving style is unsafe, interventions are made in the lateral and / or longitudinal steering of the vehicle; if the driving style is assessed as safe, only instructions are given to the driver, automatic interventions are dispensed with or their extent is limited (e.g. maximum correction value of the steering angle).
